[Fix] Revert back themes and text sheme

[xerta555]

Hi
With the last version 24.11.1, the dark theme has some drawbacks compared to the previous version (not 24.11 but the one before):

The dark and light themes have some problems compared with the previous version (not 24.11, but the one before): the file description text box no longer uses the Windows text colour, but a grey colour that I don't find very legible. The same problem applies to the light theme.

Also, the scroll bar looks like the one in Windows 11, even though I'm on Windows 10 and prefer the one in 10 to the one in 11, so it's not consistent.

The best thing would be to add an option in the interface for MediaInfo to use the colours and images defined at system level again, so that everyone is happy.

In my case, having a custom Windows theme: all this causes visibility problems whatever the predefined theme selected.

Thanks in advance.

My setup:
Windows 10 22H2

Screenshot please. The dark theme was never changed since its implementation and its colours are from Embarcadero's VCL Styles and not manually selected. On the light theme, the text colour was never changed too and should be black while only the background was changed. Scrollbars are not implemented or controlled by MediaInfo's source code as well.

OK, so I guess the problem must lie with the VCL styles in this case?

Here's how it looks on Windows 10 using the ‘Use system setting’ option:

Note the scrollbars design (Windows 11), the window borders (Windows 11 style on Windows 10 host), the text color which don't match Windows color anymore and background color which hurts my eyes as well as not being very legible, which may not look like it on the screenshot, but it is in real life.

Using the "Light" option:

Note the title bar background and color and scrollbars which are respected here
but not the file infos background color which don't use the Windows default one bcz it just use an 255, 255, 255 rgb img/color

Using the "Dark" option:

This option includes all the inconsistencies and defects of the ‘Use system setting’ option, as my Windows 10 is configured in dark mode.

The best thing, I think, would be to use the default settings of the host system, so as not to leave any imperfections that could lead to visibility problems in my case.

This is how MediaInfo 24.11.1 is supposed to look on both light and dark theme. When set to follow system setting, it is exactly the same as when setting to light or dark manually with the difference that it follows the light or dark app mode setting in the Windows settings app.

Regarding the dark theme, it is 100% VCL style. The colours and scrollbars can not be changed in code. I am not satisfied with the non-native title bar and lack of window shadows compared to the light mode as well. The background of light mode text view was changed to match the easy view background (249 ,249, 249) which is also used by many apps that do not use (255, 255, 255).

For comparison, shown below is close to how native Windows apps should look like for both modes. This is what I am 100% satisfied with.

@JeromeMartinez any idea what is going on in #951 (comment)? Seems some toolbar icons went missing too?

No idea, they are there on my side.

@cjee21 you show me your screenshoot on a Windows 11 host, I was speaking of MediaInfo on Windows 10. I even recognise the basic Windows 11 wallpaper in the background of your screenshots, whether the basic wallpaper in your examples is unchanged on Windows 11.

So you confirm to me that the problem come from the VCL style, so is it possible to <> (i use <<>> symbols here to try to explain it in another way) ?

In addition, there's something I didn't mention in my introduction: the fact that the customised dimensions of the windowed mode application are not retained after MediaInfo has been closed and then reopened. I imagine this is yet another VCL-style bug.

In conclusion, I'm open to testing a version not based on the VCL style on my Windows 10 configuration.

Best regards :)

It is never by default on any SDK as far as I know.
There is a pending PR for that.

@JeromeMartinez should we just reset the backgrounds of all the text views to VCL default which is clWindow? This way it will follow whatever colour that is defined in Windows as clWindow. This is (255, 255, 255) by default on Windows 11 and is the background colour of File Explorer etc.

I am fine with that.

[JeromeMartinez]

Maybe checking the actual color and if > 249 we set 249? So it is not too much white when white is the default and we keep other default values.

And what's possible to do about the corners of the MediaInfo window which a Windows 11 style, that don't match on Windows 10 setup ?

For scrollbars, window borders, title bar and colours of the dark mode, it is beyond my capabilities and require someone who can mess with VCL styles. I have no intention of learning more about VCL styles and prefer to learn Qt which has dark mode support by default without all these additional work.

Would replacing VCL with QT fix all these problems and inconsistencies?

We have a Qt version but we are far from ready for replacing the current GUI SDK with the Qt version.
